As the population in a region grows, the demand for water also increases. What is a possible consequence for the water resources?

Other species will have to compete more with humans for water.

Water will become more abundant because more people are using it.

Water quality will improve due to higher demand for clean water.

Water will become a non-renewable resource and run out quickly.

In science class, students learn about dead zones in the ocean. Dead zones are areas that form when excess nutrients enter the ocean, leading to oxygen depletion. Which explanation BEST describes the human industry most impacted by this?

Without adequate oxygen commercial fishing is affected because fish cannot survive.

Tourism is affected because dead zones make coastal waters less attractive.

Marine transportation is affected because dead zones alter shipping routes.

Offshore oil drilling is affected because the drilling platform requires oxygen-rich water.

In an area where groundwater is being extracted for irrigation, what must occur for the water table to stay constant?

The rate of extraction must equal the rate of replenishment.

The rate of extraction must be less than the rate of replenishment.

The rate of extraction must be greater than the rate of replenishment.

The rate of extraction must fluctuate less than the rate of replenishment.

Which actions HARM water quality? Choose TWO .

dumping industrial waste into rivers

planting trees along riverbanks

cleaning up oil spills promptly

installing water-efficient fixtures

Which of the following actions are solutions in conserving water?

Installing low-flow showerheads.

Using a hose to clean driveways.

living organisms drink water to survive.

What human activity can result in the presence of hazardous metals in drinking water?

removing fish from the water source

What human action can lead to organic substances contaminating surface water?

application of fertilizers in agriculture

mining activities near water bodies

deforestation for urban development

discharge of industrial chemicals

increasing carbon levels in water

Which human activity can lead to water pollution by introducing harmful disease causing pathogens?

allowing untreated sewage to flow into bodies of water

dumping industrial waste into rivers

using fertilizers in agriculture

What are the possible impacts of fertilizer runoff into bodies of water?

Harmful algae blooms, blocking sunlight for other organisms

Which statement BEST explains how excessive algae blooms impact the stability of the ocean system?

Excessive algae blooms can deplete oxygen levels in the water through decomposition of the algae, leading to low oxygen levels and negatively impacting marine life.

Algae blooms have no impact on the stability of the ocean system.

Excessive algae blooms increase oxygen levels in the water, benefiting marine life.

Algae blooms lead to a decrease in hydrogen in the water, affecting marine ecosystems.
